Simplicity DC Return Pump
The Simplicity DC Return Pump is a quiet, energy-efficient, and fully controllable pump for your sump return, closed loop, or manifold. Every model includes a digital controller with adjustable flow and a Feed Mode, runs on safe low-voltage 24V DC, and comes with both threaded and barbed fittings for easy plumbing. Four sizes cover reef and freshwater systems from about 50 to 320 gallons. Explore more of our reef and aquarium gear.
How It Works
A return pump moves water from your sump back up to the display tank. The Simplicity DC pump uses an efficient, controllable DC motor so you can dial in the exact flow your system needs, then run it quietly and cool. The included digital controller sets the flow rate and triggers Feed Mode, and the threaded plus stepped-barb fittings adapt the output to hard PVC or flexible tubing.

Sizing Your Return Pump
Pick your pump by the total head height of your return, not just the flow number. Head is the vertical distance the pump lifts water plus the losses from elbows, unions, and a nozzle, so the real flow at the top of your tank is lower than the maximum rating. Choose a model whose head comfortably exceeds your run and whose max flow gives you the turnover you want after those losses.
FAQ
Is a controller included?
Yes. Every model ships with a digital controller that sets the flow rate and has a Feed Mode.
Does it run in the sump?
Yes. These are submersible pumps designed to run in a sump. Do not run the pump dry.
What fittings come with it?
A threaded union sized to the model plus a set of stepped barbed fittings, so it adapts to PVC or flexible tubing.
Freshwater or saltwater?
Both. The Simplicity DC pump is rated for freshwater, saltwater, reef, and brackish systems.
